Presentation Transcript

  1. GUS We have created the Genomic Unified Schema (GUS), a relational database that warehouses and integrates biological sequence, sequence annotation, and gene expression data from a large number of heterogeneous sources. User-friendly web interfaces present slices of the GUS database and allow researchers to execute structured queries for information concerning gene structure, function, and expression. Please visit poster #146A for details of the Genomics Unified Schema (GUS).

  2. GUS Supports Multiple Projects AllGenes Allgenes is based on a comprehensive mouse and human gene index. The genes are approximated by transcripts predicted from EST and mRNA clustering PlasmoDB PlasmoDB is the official database of the Plasmodium falciparum genome project which provides an integrated view of genome sequence data including expression data from EST, SAGE, and microarray projects EPConDB EPConDB is an index of genes expressed in endocrine pancreas. Expression is defined either through microarray experiments or sequence annotation.

  3. allgenes.org query "Is my cDNA similar to any mouse genes that are predicted to encode transcription factors and have been localized to mouse chromosome 5?" This query illustrates several aspects of the GUS database including: http://www.allgenes.org/

  4. Select the allgenes.org boolean query page Click on the "AND" button

  5. Choose the RH map and GO function queries Select mouse chromosome 5 and "transcription factor"

  6. There are 22 mouse RNAs (assemblies) that meet these criteria: This query result set now appears on the query "history" page:

  7. Now use the BLAST page to identify RNAs similar to my cDNA The results of the BLAST search appear in the query history

  8. Intersect ("AND") the BLAST search with the previous query: And we have our answer (the third row on the query history page):

  9. Other transcripts from the same gene Predicted GO function(s) (some manually reviewed) External links Mapping information Protein/motif hits Gene trap insertions, etc. UCSC BLAT CAP4 assembly EST expression profile predicted protein

  10. PlasmoDB query: "List all genes whose proteins are predicted to contain a signal peptide and for which there is evidence that they are expressed in Plasmodium falciparum's late schizont stage." This query illustrates several aspects of the GUS database including: http://plasmodb.org/

  11. Select Text Search from the PlasmoDB homepage Choose signal peptide

  12. Choose chromosome and Gene/prediction type-submit There are 1952 genes with predicted signal peptides

  13. Choose gene expression-microarray from the homepage Then choose an experiment, chromosome, and Gene/prediction type - submit There are 12170 gene predictions that satisfy this query

  14. Go to the history page and choose which simple queries to combine. Select intersect. We have an answer. There are 949 predicted genes that satisfy our complex query Click on a gene to get a full report

  15. There is a variety of information available from the report page including: Gene models predicted using a variety of approaches and mRNA and protein predictions

  16. EPConDB query: "Which DOTS assemblies (RNA) represented on the Endocrine Pancreas Consortium’s chip 2.0 are constituents of the insulin initiated signal transduction pathway ?" http://www.cbil.upenn.edu/EPConDB

  17. Go to the gene information query page and click on “DOTS assemblies involved in a pathway”

  18. Choose the insulin pathway, a p-value, pancreas, the species, and whether an assembly must include an mRNA - submit There are 59 dots assemblies that are constituents of the insulin pathway

  19. Return to the gene information query page and select clones sets. Choose chip 2.0 - submit There are 3242 assemblies represented on chip 2

  20. Go to the history page, select the queries to combine and select intersect – view the results There are 8 assemblies that satisfy the complex query. Clicking on an RNA retrieves an allgenes report.
